COOLING CHAMBER FOR SMOKING PIPES.

Application filed January 3, 1,928. Serial No. 244,169.

My invention relates to cooling chambers for smoking pipes, the purpose of which is to decrease the temperature of the smoke as it passes from the bowl in which the tobacco is burnt to the mouth of the smoker; and the objects of my invention are, lirst, to provide a cooling chamber which, though simple in construction, affords eicient cooling means in a limited space, secon d, to cause a whirling circulation of the smoke in the cooling chamber so as to bring all parts of the smoke into contact vith the cooling walls Jrhird, to otter to the smoker the simplest p i )le means for cleansing the walls of the cooling chamber and for thus preventing the deposit of insulating layers which impair the heat dissipating faculties of the walls ot said chamber; fourth to effectively repiace the long pipe stem which formerly was used; and fifth, to provide a convenient container for means for filtering the smoke.

lVith these objects in mind, I have invented these improvements and I attain these objects lby the means illustrated in the accompanying drawing, in which- Figure 1 is a sectional side view of a pipe showing my improvements embodied in the pipe.

Figure 2 shows a separate view of my cooling chamber, illustrating in particular the large inner cooling surface indicated by a dotted line.

Figure 3 shows a separate view of the bushing by means of which my invention is assembled to a pipe.

Similar numerals refer to similar parts throughout the several views.

A tenen 6 on the mouth-piece 4 fits the hole 7 in the stem 8 on bowl 5. Small canals 9, 9 in the two parts l and 8 serve for the passage of. the smoke. Between these t-wo parts I have inserted my invention, consisting of a tube 10, which represents the cooling chamber and a connecting bushing 11. The small hole 12 through the bushing 11 corresponds in size to the holes 9, 9 and it terminates in the sharp edge 13.

The large diameter of the inside 14 of the cooling chamber 10, equals the outside diameter of tenon G and of bushing 11, as well as the diameter of the hole 7 in the stem 8 on the bowl; all these parts are assembled with push tit; a small thumb-set-screw 15 allows setting of the bushing 11 in the cooling chamber 10. The purpose of this screw is to permit bushing 11 to pull out of stem 8,-in which it may become settighter than in the cooling chamber on account of charring and because of adhesion by the saliva,-when the pipe is to be disassembled, before the connection is severed between the bushing and the cooling chamber. l

As a material for my cooling chamber, I use bibulous or molded materials7 or other compounds, minerals or wood which are well known to the art and which are suited for the purpose on account of their conductive capacity. Since the opening in the cooling chamber is made as large as possible and the wall is kept as thin as possible, I provide thin metal sleeves on the ends of the cooling chamber, 16, 16, when the characteristics of the material used for the chamber might allow breakor splitting at the ends. lVhen I use metal or other substantial materials for the chamber', such a sleeve, 16, is not necessary.

The sharp edges on the holes on the tenon and on the bushing, 18, issuing into the large cooling compartment, impart a whirling motion to the smoke as it passes through, causing all its parts to come into contact with the cooling surface. Since the inside wall of the cooling compartment represents a straight wall, it may very easily be kept clear of deposits.

I claim 1. In combination with a smoking pipe characterized by a. perforated mouth-piece with a tenon on the end and a bowl with a stem, counterbored to fit over said tenon, a straight round bushing to fit into the hole in said stem, a straight round sleeve with an inside diameter to lit over said tenon and said bushing, and means for setting said bushing in said sleeve.

2. A replaceable cooling chamber for smoking` pipes in which the stem is detachably jointed by a tenon, consisting of a sleeve with a straight bore fitting over said tenon, a straight bushing fitting into said sleeve and a set-screw on the end of said sleeve for fastening said bushing in said sleeve,
